Recently I grabbed some preconfigured CentOS 5.0 instance from EC2 and installed our stuff on it from rightscale. The instance was a little old, but I assumed that it would be up to date after a single yum upgrade.
However, for reasons beyond my understanding, CentOS is not updated beyond 5.0:
[root@ip-10-102-63-111:~] yum upgrade
Loading "installonlyn" plugin
Setting up Upgrade Process
Setting up repositories
Reading repository metadata in from local files
No Packages marked for Update/Obsoletion
[root@ip-10-102-63-111:~] cat /etc/redhat-release
CentOS release 5.0 (Final)
The repositories are active and even my EPEL packages are being updated, but it seems that the person who created this instance somehow fixed it at 5.0. However, I really need to update to the latest 5.x. How can I get yum upgrade to work again?
